What is the definition of a 'major defect' when examining a wheel?

A 'major defect' in the context of examining a wheel refers specifically to significant issues that could compromise the safety and functionality of the vehicle. This includes conditions such as cracks, breaks, or noticeable damage to the wheel itself. These types of defects can lead to catastrophic failures, such as a wheel collapsing while driving, which presents a direct danger to the driver and others on the road.

In contrast, cosmetic imperfections, minor scratches, or normal wear and tear do not affect the structural integrity of the wheel. These conditions might impact aesthetics or indicate a minor degree of wear over time, but they do not inherently pose a hazardous situation. Recognizing a major defect is crucial for ensuring that the vehicle remains safe and operable, making the identification of cracks or significant damage paramount during an inspection.
